SINGER Jennifer Lopez has given birth to twins, according to People magazine, which has reportedly paid as much as $US6 million ($6.5 million) for the photo rights.

The boy and girl, delivered in a Long Island, New York hospital today, were the first for the 38-year-old actress and singer.< p>

Her husband Marc Anthony, a 39-year-old salsa singer, has a daughter and two sons from two previous relationships.

Lopez did not confirm her much-rumoured pregnancy until early November, when she announced the news to a Miami audience while on a concert tour with her husband.

The trade publication Advertising Age reported earlier this week that People magazine was poised to pay the couple between $US4 million and $US6 million ($4.3 million and $6.5 million) for exclusive US rights to the first photos of the twins.
